FOND DU LAC, Wis. (AP) – Fond du Lac deputies investigating a 1990 homicide have gathered evidence that may incriminate a Kenosha man. A Reporter Media report says the 1990 death of Berit Beck confounded authorities for decades. But now the Fond du Lac County sheriff’s office says a new analysis suggests the man had been in Beck’s van. Beck was an 18-year-old Sturtevant woman. She was found slain in a Waupun ditch, and evidence recovered from her van was inconclusive. But deputies have now identified a primary suspect, and say they have tangible evidence that links him to the inside of the van. Sheriff Mick Fink declined to elaborate over the weekend, but a news conference is scheduled for Monday morning. Investigators have spoken with the man but he was not in custody Sunday.
